Does the patron (Maula) inherit from his freed slave's descendants (from below)?
Chapter on Inheritance of Wala'
Al-Mughni
Book of Walā' (Patronage)
Primary text
The general consensus of the scholars holds that the patron (Maula) does not inherit from the descendants of the slave he freed. The evidence for this position is the Prophet's saying: "The loyalty (Wala) belongs only to the one who manumits." Furthermore, since the patron did not bestow a favor upon the freed slave in the sense that necessitates inheritance, he does not inherit from him, similar to a stranger. The action of the Prophet (peace be upon him) in the related case is considered a specific ruling (qadiyya fi 'ayn), which may imply the inheritor inherited through a relationship other than manumission, or that the manumission itself did not bar him from inheritance, or that the gift was merely an act of connection and favor.

Shurayh and Tawus held that the patron does inherit from his freed slave's descendants. They based this on a narration from Ibn Abbas, stating that when a man died during the time of the Prophet, leaving no heir except a slave he had freed, the Prophet gave him the inheritance. Al-Tirmidhi classified this hadith as Hasan (good).
